Vorrichtung zum Herausschneiden von abnormalem Gewebe im menschlichen Verdauungskanal

摘要

A method of removing abnormal tissue from the gastrointestinal tract of a patient, comprises the steps of introducing an endoscope (10) into the patient's gastrointestinal tract and applying suction to such abnormal tissue to pull the abnormal tissue into a ligator at the distal end of said endoscope (10). A ligation band (20) is then applied to the base of the abnormal tissue within the ligator to form a polyp. An electro-surgical snare is then used to sever the polyp from the surrounding tissue.
